The monthly Power Cost Equalization (PCE) reports indicate an average power line loss of 26.55%. This loss is unreasonably = considering the voltage of the power distribution system. A survey of the distribution system metering revealed the following problems: 1. Wiring of the meter socket at the school service was incorrect. The meter socket wiring was changed so the meter operates correctly, however, the meter installation should be rewired to include current transformer shorting switches. The meter multiplier for the school is 40. School metering information was not included on the PCE reports from which the line losses are calculated. 2. The power plant station service meter is improper for this application. The meter should be a 120 volt, form 12s network meter. 3. Street lighting was not metered and was included as line loss. 4. The utility supplies free service to the two plant operators. Although this energy was metered, it was not included as station service use on the PCE report and thus became part of the net line loss. 5. The utility supplies free service to the = church and parsonage. Although the energy is metered, it has not been included on the PCE report as sold energy or as station service use and thus became part of the net line loss. Addressing the metering problems outlined above will in all likelihood reduce the line losses to a reasonable level. Background: RSA Engineering, Inc. was given a work order under their open end contract with the Alaska Energy Authority to perform a line loss study for the City of Akiak, Alaska. RSA Engineering, Inc. hired Craig Thompson of Thompson Engineering, Inc. to perform the actual site visit and provide the initial field report. Mr. Thompson travelled to Akiak on July 19, 1990. Upon arrival, he met with the utility bookkeeper, Mrs. Lily Ivan ers hh 18) and one of the utility’s two plant operators, Mr. Emil Williams (photograph 19) and discussed the purpose of his visit. Mr. Thompson explained that he was in Akiak ___ to review the distribution system and make recommendations, including cost estimates for improvements. Mrs. Ivan agreed to make copies of the past six months of the utility reports, and consumer metering data for those same months while Mr. Williams and Mr. Thompson reviewed the metering installations in the village. Mr. Williams and Mrs. Ivan indicated rr were very much concerned over the potential loss of Power Cost Equalization (PCE) due to high line losses. System Review: Copies of the data compiled by the utility on consumer energy use in Akiak for the months of January through June of 1990 are attached in Appendix A. System generation and sales data compiled from utility records for the first six months of 1990 are summarized below: KWH KWH KWH 1990 SYSTEM SELF SYSTEM KWH PERCENT MONTH GEN USE USE LOSS LOSS January 35,646 1,052 23,424 11,170 31.34 February 34,414 602 25,556 8,256 23.99 March 31,751 255 24,087 7,439 23.43 ril 27,396 238 21,536 5,622 20.52 ay 27,156 283 20,419 6,454 23.77 June 29,654 249 18,655 10,750 36.25 Average: 26.55 A brief review of the distribution system was conducted, and it was apparent that a line loss averaging 26.55% (6 months) is unreasonable. The Akiak power system consists of the single power plant and a three phase delta 2.4 kV overhead distribution system. The power plant consists of two diesel powered engine generator sets located in a wood frame building (see photographs 1 through 5). One noticeable drawback to the present location of the power plant is that it is not in close proximity to a school -2- or community building that could make use of waste heat from the facility. The system peak load is approximately 100 kW without the school load attached. With the low system load and = voltage distribution system (see photographs 6 through 8), it was determined that a sizeable portion of the losses Akiak was experiencing were most likely due to metering losses rather than line losses. Using the criteria that a line loss of less than 5% is resonable for a system the size of Akiak’s, the magnitude of metering error is estimated to average 7800 kWH per month. Residential consumers average less than 400 kWH use per month so a review all three phase, and large consumer metering installations was undertaken. In reviewing the line loss figures with Mr. Williams, it was discovered that the village had, in addition to the Snes ae only two large consumers (one three phase, and one single phase) meter installations. These are the school complex and the community building. A discussion of each of these meter installations follows: 1. Power Plant (see photographs 4 and 5): The kW meter in the power plant is a Crompton panel meter with a secondary readout that shows kWH (see photograph 5). The current transformers in the plant panel were 600:5 ratio, model number 4TC16, manufactured by Midwest Electric. The wiring on the kW-kWH meter could not be verified (no wiring diagram), however, the current level in each phase was checked and the instantaneous kW calculated from these readings matched closely with the panel meter reading. Although the Crompton meter is adequate for the function it now performs, it is not designed to be a revenue class meter. Specifically, main generator, station service, feeder and consumer metering installations traditionally have been designed so that the meter can be removed from the meter socket. This allows those without a great deal of technical expertise to easily replace this meter with a spare (such as would be done during the regularly scheduled calibration testing). It is recommended the utility install a socket based kWH/demand meter in the generator switchgear and that the utility maintain a spare meter for this installation. The power plant did have a station service meter (no photo). The meter is a single phase 240 volt, class 200, form 2s, type J4S meter manufactured by Sangamo. The power plant generation voltage is 120/208 three phase, and the Station service meter is attached to the generation bus, therefore, the present Station service meter is not appropriate for this application. A 5 jaw, network meter, form 12s should be installed in place of the existing meter. This can be accomplished fairly inexpensively by installing the new meter in the existing 4 jaw meter and using a clip-on type fifth jaw. 2. Community Building: The community hall and its meter is shown in hotographs 9 and 10. This single phase meter was added to the system in ebruary of 1990. The meter multiplier was verified to be correct (80) with the CT ratio of 400:5. Current readings were taken on each phase, and the disk rotation timed. These tests indicate that the meter is operating properly. <3 3. School Building (see photographs 11 through 14): The meter for the school serves not only the high school but also the grade schools, maintenance buildings and some teacher housing. The school meter wiring was installed in November of 1989. Prior to that time, the meter multiplier on the school meter was 80. New metering was installed along with new school generators when fires destroyed the previous units. The new meter is a General Electric type VM-65-S, class 10, 120 volt, form 6s meter, serial number 82707978 with current transformers rated at 200:5. The meter multiplier is 40. Current readings were taken on each phase and the disk rotation timed. These tests indicated that the meter was reading only 60 to 70% of the actual load. The meter wiring was reviewed and several errors were discovered. Figure 1 shows how the meter was wired when initially found. After careful comparison to the correct wiring diagram shown in Figure 2, it can be seen that: a. the polarities are reversed on the secondary side of the current transformers. b. _ the current connections at the meter of phases A and B are reversed. c. the voltage connections at the meter of phases A and C are reversed. Figure 3 shows an alternate functional wiring for proper operation of the meter. The meter was rewired in this manner because it required no additional material, and the wire and connectors were not available to connect the meter as shown in Figure 2. Current readings were taken again on each phase and the disk rotation timed. These tests indicated that the meter was operating correctly. Although the meter was reading approximately 33% low when initially tested, the —_ inaccuracy would vary with phase loading and cannot be determined as an absolute. It is recommend that the utility (or school) have the meter rewired as shown in Figure 2, and that current transformer shorting switches similar to the Multiamp-States model SMH 410-E be installed in the circuit (see Appendix B for catalog cut on this item). This will allow the meter to be removed without disturbing the ned supply to the school and without damage to the current transformers. It is also recommended that the utility purchase a spare meter ~ this installation which will enable regular calibration tests to be made on e meter. Mr. Williams indicated that he sometimes had difficulty reading the dial type registers, but that because he reviewed all readings, he was able to catch any errors. He also indicated that the utility did not have a program for periodically checking the calibration of the plant meters or any of the system meters, and the city did not own a substitute for each type meter used in town. xi[__ [x2 nt >C XU dX ee +B LOAD xif [x2 = >A —>N FIGURE 1, AKIAK SCHOOL METER AS FOUND METER BASE ——~' +B LOAD FIGURE 2, CORRECT METER CONNECTIONS METER BASE ——~ METER BASE IGURE 3 ALTERNATE FUNCTIONAL CONNECTIONS In addition to the three phase and large load metering installations, several other metering discrepancies were discovered during the course of the review. These are discussed below: as Street Lights: During the walk-thru the city, it was noted that the street lighting was unmetered and several of the street lights were operating continuously (see photographs 6 through 8). In discussing this with Mr. Williams, it was learned that there were 18 total street lights operational and of these, 2 were on at all times with the remainder operated vis photo cells. It was also learned that the utility absorbed all the energy cost for the street lighting, and it was not accounted for separately and it was, therefore, part of the line loss. An estimated energy use for the street lighting, during a winter month is shown below. (18ea * 175watt * 720 hrs/month)/1000 = kWH/month = 2268 kWH/month for those months when street lights are on constantly During the winter, this is a he crop part of what was being called line loss. This problem was discussed with Mr. Williams, and it was explained that standard an practice was to meter at least one street light and to estimate the other (different wattage) street lights energy use from the metered data. The utility will require some assistance from the Alaska Energy Authority to = which category this energy should be included in on the monthly PCE orm. Station Service: As discussed previously, the present power plant has a station service meter, however, the utility also provides the power plant operators electric power at no cost. The a total combined operator use (2 operators) over the last six months has been 1594 kWH per month. This also is a significant part of what is being called line loss. This energy should be included in the station service category on the monthly PCE form. Church and Parsonage: eg | discussions with the utility bookkeeper Mrs. Ivan, it was learned that the village church and parsonage were also receiving free electrical service. The average total church and parsonage (combined) use over the past six months has been 598 kWH per month. The utility will require some assistance from the Alaska Energy Authority to clarify which category this energy should be included in on the monthly PCE form. Conclusion and Recommendations: He The meter installation at the school service should be rewired to match the shown in Figure 2 and current transformer shorting switches (similar to - Aultiamp-States Sods! SMH 410-E shown in Appendix By should be aed 4 in e circuit. The station service meter in the power plant should be changed to a 5 jaw type, form 12s, 120 volt. A meter should be installed on one street light to more accurately determine actual energy use. The Alaska Energy Authority should be consulted to determine into which category this energy should be included. The utility should repair the photo electric cells on the two street lights that are now on constantly. The energy use of the utility's operators should be treated as station service load and included as such on the monthly PCE form. The utility should ove for the energy used by the church and parsonage. duane: the Alaska Energy Authority should be consulted to determine into which category this energy should be included. It is recommended the utility install a socket based kWH/demand meter in the generator switchgear. The utility power urchase a spare meter for the community building, the school, the pow <y and the power plant station service (normal practice dictates het a. a ‘* ly have on hand spare residential meters). The utility should also periodically have all meters tested for accuracy. Standard industry poe sets a goal of calibration checking each meter every five years, jowever, meter readers and office help should be alerted to point out any large discrepancies noted in monthly use.

Safety-grip handle Special angled blade Corregated test lugs One-piece jaw & hinge This new line of States® test switches combines over 60 years of experience in the design and manufacture of test switches with the latest improvements in material composition and construction techniques. A complete line of switches is available for meter, relay, instrument, transducer and control system calibration, disconnecting, trouble-shooting, check-out and testing.

Each switch blade may be operated independently or, where requirements dictate, adjacent handles can be ganged for simultaneous operation. Many features are incorporated for increased safety, durability, ruggedness and reliability. Where applicable, dimensions are in accordanc: with EEI-AEIC Meter and Service Committee Standards. Standard Features Self-Extinguishing Materials All non-metallic components are made of self-extinguishing, flame-retardant materials with Underwriters’ Laboratories’ best rating for self- extinguishing materials, V-O. Non-Ferrous Material All current-carrying metallic components, including hardware, are made of highest quality non-ferrous materials such as copper, bronze, brass or phosphor bronze. This ensures excellent conductivity and minimizes corrosion and galvanic action between dissimilar metals. Nickel-Plating All metallic components, including hardware, have a corrosion-resistant nickel finish which ensures good electrical contact and smooth operation of moving parts even after years of inactivity. Safety-Grip Handle The molded handle covers the terminal and includes a lower lip which projects over the metal parts of the switch, thus protecting the operator from contact with live components. One-Piece Jaw and Hinge One-piece construction of hinge and jaw with wire holder eleminates unnecessary, multiple connection points. Bases Type SMH test switches are available in one-, two-, three-, four-, seven-, and ten- pole base sizes. The bases are made of rugged 3/4-inch, non-tracking material with excellent Special Blade Shape All blades are shaped so that the edge of the blade enters at a right angle to the jaw; thus, the blade enters and exits the full width of the jaw simul- taneously. Test Lugs The large corrugated test lug provided for each terminal stud is a secure surface for attaching test clips. Switch Jaws States® test switches have uniform contact pressure over the full width of the blade. The ‘“‘ping” heard when opening the blade is due to the special, spring grade phosphor bronze used in the jaw. This design ensures an excellent low-resistant contact which will not overheat. insulating properties and are impervious to moisture. Mounting dimensions of the four-, seven-, and ten- pole bases conform to applicable EEI-AEIC Meter and Service Committee Standards. \. ia i High Barriers Maximum circuit isolation is obtained by the extra-high barriers which provide uncompromised protection. Barriers are permanently mounted and cannot fall out or be knocked out, as in some “snap-in’’ designs. Short-Circuit Jaw A rugged, make-before-break element is utilized to short the secondary of a current transformer. Fixed Terminal Studs The screw terminals on which wiring connections are made are a part of a rigid, immovable assembly and cannot be turned or backed-out. Test Jack Eliminates the possibility of opening CT secondaries and permits safe, easy measurements to be made in current circuits without disturbing permanent wiring. A dual-circuit test plug, such as States Catalog #1011-K, is inserted into the test jack, thus putting the measuring instrument in series with the current circuit. The test jack is not used to carry current except when making a test since it is shunted by a standard switch blade that is opened only when the test is used. See photo on page 7. Color-Coded Handles Unless otherwise specified, potential elements have red handles and current elements have black; however, the following other colors are available at additional cost: blue, orange, white, yellow, brown, green, black and white, or red and black. Identification Card Holder Each safety grip handle is slotted for insertion of an identification card for marking or coding. Cards are available from States under Part #SB 678.
